IMPROVEMENT IN SHIRT-STUDS AND SLEEVE-BUTTONS.

Specication forming part of Letters Patent No. 131,023, dated September 3, 1872.

' To all whom it may concern:

Beit known that I, J oEN P. ONDERDONK, of the city and county of l?hiladelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Shirt-Studs and Sleeve-Buttons, and other metallic ornaments and articles of jewelry; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the said invention, reference being had to the accompanying drawing which represents my improvement applied to two of the ordinary forms of sleeve-buttons.

The object of this invention is to prevent the blackening of shirt-fronts, Wristbands, and other parts of the clothing, caused by contact with metallic surfaces.

Shirt-fronts, cuffs, &c., are apt to be blackened by the inner surfaces of studs and buttons rubbing against them, the effect of which is often unsightly, and gives trouble to remove in washing. Y

To obviate such inconvenience is the design of this invention, which consists in enameling those surfaces ofA gold or other jewelry which come in contact with such parts of the clothing as it may be desired to protect. The said surfaces may be enameled in the ordinary Way or coated with any substance which will not rub off or disiigure the clothing.

In sleeve-buttons and studs it will usually be sufficient to enamel the inner surface of the outer button, as well as the shank. This method is shown in the drawing, the enameled parts being shaded.

What I claim as my invention, and desire to secure by Letters Patent of the United States, is-

As a new article of manufacture, a stud, button, metallic ornament, or article of jewelry, the inner surface of which is enameled, either in whole or in part, substantially as and for the purpose described.
